Specification of Letters Patent.

Patented Oct. 8,1912.

Application filed April 6, 1912. Serial No. 689,010.

To all whom it may concern:

Be it known that LVViLLIAM HENRYCQN- RAD, a citizen of the UnitedStates, residing at Villiamstown, in the county of Grant and i State ofKentucky, have invented certain new and useful Improvements in Hasp-Locks, of which the following is a specification, reference being had tothe accompany ing drawings.

This invention relates to new and useful improvements in locks, andparticularly to astenings for hasps and the like. It 1s used infastening doors, gates, etc., by providing a hasp with a slot adapted toreceive a staple, and, after the hasp has been placed over t-he staple,passing the bolt of a padlock through that part of the staple whichprojects beyond the hasp. The hasp must be first placed over the staple,then the padlock applied, and, in many cases, the hasp and staple mustbe held together with one hand while'the lock is placed in position withthe other, and even after this locking has been effected, both thestaple and the padlock bar are exposed so that it is not difficult tofile eithery apart. To obviate these diilicultles locks have been formedimmediately upon the hasps and my invention consists in the arrangementof parts in such locks, though, of course, it will be readily understoodthat the same arrangement may be applied to otherl forms of locks.

The object oit the invention is to provide a combined latch and lockwhich will possess advantages in points of e'lliciencyl and durability,is inexpensive of manufacture and at the same time is simple inconstruction and operation.

With the above and other objects in view the invention consists in thenovel features of construction and the combination and arrangement ofparts hereinafter more fully described, pointed out in the claims andshown in the accompanying drawings, in which:

Figure 1 is a perspective view of my improved lock showing theapplication of the same; Fig. 2 is a plan view of the lock with the haspremoved to expose the working parts; Fig. 3 is a sectional view on theline 3 8 of Fig. 2; and Fig. 4 is a sectional view on the line 4-4 ofFig. 2.

Referring more particularly to the drawings 1 indicates a hasp and 2 astaple both of any well known construction. The hasp is provided at oneend as usual with a slot 3 for the reception oi' the staple, and withrelation to this slot a lock is so placed that its locking bolt 4 passesacross it, thus engaging the staple when in position for fastening.

It will be noticed that by reference to the drawings, the lock casingcomprises an elongated body portion 5 provided with an angular extension6 which is recessed on its underside as shown at 7 to receive the bolt4. The hasp 1 is also provided with an extension 8 coincident with theextension on the body 6 and is recessed as shown at 9 to receive aportion of the locking bolt and the coil spring 10 which is mounted uponthe bolt, said spring being disposed between the shoulders 11 and theinner head 12 of the bolt and adapted to normally hold the bolt in aclosed position.

It will be seen that the body oi the casing at the intersection oi theextension 6 and the body is enlarged and provided with an arcuate recess13 to receive the staple 2 and entirely inclose the same. Communicatingwith (he recess 13 and formed on the underside of the body 5 is anelongated recess 14 adapted to receive the sliding tumbler 15. Thetumbler 15 comprises the body portion 1G bifurcated at one end to formthe spaced arms 17, and provided at the other end with an elongatedextension 18 arranged at one side ot the tumbler and adapted t0 engagein the recess 19 in the head 12 to hold the bolt 4 against movement. Oneof the arms 17 is provided on its outer side with a plurality of notches20 adapted'to receive the lug 21 extending inwardly from one side ot'the recess14, said arm being held securely into engagement with the lugby means ot' the spring 22 arranged bet-Ween the arms. The other of thearms 17 opposite the notched arm is provided on its outer face with ashoulder 23 adapted to be engaged by the inner end of the pivoted catch24 to force the tumbler toward the end of the locking bolt, the end ofthe extension 18, engaging in the recess 19 to hold the bolt in a lockedposition.

The body of the tumbler is provided upon one edge with an inwardlyextending recess 25 adapted to receive a key which is inserted inthrough the opening 26 in the casing, the lugs on the key engaging theside walls of the recess to slide the tumbler and lock and unlock thebolt 4. The bolt 4 is provided on its outer end with a head 27 Jforminga suitable finger hold to manipulate the bolt.

From the above it Will be readily apparent that when the hasp isarranged over the staple, the staple protruding through the slot 3 andinto the recess 13, the bolt 4: is released, the spring 10 forcing thebolt into position. The catch 24 may be manipulated, if the operatordoes not happen to have a key handy, to force the tumbler 15 toward thebolt so that the extension 18 Will engage in the recess 19 to hold thebolt in a locked position, the lug 21 engaging in one of the notches 20to hold the tumbler in its locking position. 1t Will be readily seenthat the catch 24 can only be used to lock the bolt and cannot be usedto unlock the same.

From the above it will be readily seen that 1 have provided an improvedhasp fastener having a lock Which is inclosed in a casing to protect thesame from rain or snowT to prevent any of the Working parts of the lockfrom becoming rusty.

While l have shown and described the preferred form of my invention itWill be obvious that various changes in the details of construct-ion andin the proportions may be resorted to for successfully carrying myinvention into practice Withoutv sacriicing any of the novel features ordeparting` fro-m the scope thereof.

Having thus described the invention what is claimed is:

l. In combination With a hasp, having a slot formed in one end thereof,and a staple adapted to be disposed in said slot, of a casing mountedupon one end of the hasp, a spring controlled bolt slidably mounted insaid casing and adapted to be disposed through the staple, a slidingtumbler mounted in the casing, an extension formed on said tumbler andadapted to engage the bolt to hold the same in a locked position, meansfor forcing said tumbler into itslocking position.

2. In combination With a hasp, having a slot formed in one end thereof,anda staple adapted to be disposed in said slot, of a casing mountedupon one end of the hasp and arranged over the slot, a spring controlledbolt slidably mounted in the casing and adapted to be disposed throughthe staple, a sliding tumbler mounted in the casing, said tumblercomprising a body portion, spaced arms formed at one end thereof, anextension formed on the other end of the body and adapted to engage thebolt to hold the same in a locked position, one of said arms havingrecesses formed on the outer side thereof, a lug formed on the cas- -fing to engage in said recesses to hold the tumbler in a locked andunlocked position, a spring arranged between and bearing against theouter ends of said arms, and

means for actuating the tumbler to lock and j -j unlock the bolt.

3. ln combination With a hasp, having a slot formed in one end thereof,and a staple adapted to be disposed in said slot, of a casing mountedupon one end of the hasp, a i j spring controlled bolt slidably mountedin said casing and adapted to be disposed through the staple, a slidingtumbler mounted in the casing, said tumbler comprising a body portion,spaced arms formed at one n end thereof, a shoulder formed on the o-uterface of one of said arms, a catch carried by the casing and adapted toengage said shoulder for forcing the tumbler into its locking position,a spring arranged between and bearing against the outer ends of saidarms and means for actuating the ltumbler and unlocking the same.

In testimony whereof -1 hereunto aHX my signature in the presence of tWoWitnesses.
